| Abstract: | In the hardware system designing of solder paste three-dimensional testers based on grating projection phase measuring profilometry, the adoption of conventional calibration method in the control of grating phase-shifting piezoelectric nonlinearity, hysteresis and creep effect can result in great error in voltage control. The adoption of the method based on gray level image matching for piezoelectric ceramic control voltage value determination and correction can improve the control precision. Experimental results show the effectiveness of the method. |
